Asymmetric supercapacitors fabricated with ferrite/CHTL-derived hydrochar electrodes

Huynh K., Maddipudi B., Amar V.S., Shende A., Shende R., Shende A., Shende R., South Dakota School of Mines and Technology, US

Scientific community is striving for novel energy storage devices with superior power/energy density. Among these devices, asymmetric supercapacitors (ASCs) typically have higher power density as compared to batteries whereas higher energy density as compared to [...]

Effect of Biochar Loading on Carbon Nanofibrous Sponge Produced from Biochar and Electrospun Polymer Nanofibers

Numan-Al-Mobin A.M., Maddipudi B., Amar V.S., Shende R.V., Fong H., South Dakota School of Mines and Technology, US

The goal of this study is to process a typical waste product, namely the biochar obtained from the oxygen-limited hydrothermal system of biomass (e.g., corn stover), into the value-added product. Particularly, the 3D carbon nanofibrous [...]

HTL Derived Biochar for Supercapacitor Electrodes

Huynh K., Maddipudi B.K., Amar V.S., Houck J.D., Shende R.V., South Dakota School of Mines and Technology, US

In this study, biochar samples were prepared by conversion of biomass feedstock (corn stover) via catalytic hydrothermal liquefaction (HTL) and later used as electrode material in conjunction with sol-gel derived perovskite based mixed (Mn,Ti)-oxides (Mn:Ti [...]

Cobalt Doped (Mn,Ti)- Oxides for Supercapacitors

Houck J.D., Amar V.S., Shende R.V., South Dakota School of Mines and Technology, US

In this investigation, a (Mn,Ti)-oxide (Mn:Ti 65:35 wt%) was prepared using surfactant templating assisted sol-gel method. To prepare this nanocomposite, sol-A with Ti precursor and sol-B containing Mn precursor were separately prepared using the required [...]

Hydrogen Generation from Thermochemical Water-Splitting Using Core Shell Ni-Ferrite/Y2O3 Nanoparticles

Amar V.S., Shende R.V., South Dakota School of Mines & Technology, US

During thermochemical water-splitting process for hydrogen generation,ferritenanoparticles undergo significant grain growth that reduces their surface area and affect the porous morphology. Consequently, hydrogen volume generation diminishes with increase in thermochemical cycles. In order to mitigate [...]
